Writing Equations

A helicopter hovers 40 ft above the ground. Then the helicopter climbs at a rate of 21 ft/s. Write a rule that represents the helicopter’s height h above the ground as a function of time t. 

• h = 40t + 21
• h = 21t + 40
• h = -40t + 21
• h = -21t + 40

A team of divers assembles at an elevation of -10 ft relative to the surface of the water. Then the team dives at a rate of -50 ft per min. Write a rule that represents the team’s depth d as a function of time t. 

• d = -50t
• d = -10t - 50
• d = -50t - 10
• d = -10t
